Sonar ant task fails with Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found exception - sonarqube

Question

I am trying to run sonar ant task on Bamboo machine. The same task works fine on my local machine (ant version 1.9.3 as well as ant version 1.8.2) but fails on bamboo ant 1.8.2 with following error

I have tried putting xercesImpl.jar in ant classpath

Answer 1

I had a similar issue running sonarqube 4.2 where findbugs would fail due to the missing parser. I was able to solve the issues by placing the xercesImpl.jar in the [sonar.home]/web/WEB-INF/lib folder and restarting the server. Once all other dependency issues were resolved by placing other needed jars in the same location, the issue disappeared.
Hope this helps.

Answer 2

I had exactly the same issue, also using Bamboo and the sonar Ant task.
I found that it was because I had run ant with an old java version. I switched from 1.6 to 1.7 and the issue was resolved.
Hope this helps someone in the future.
